[ Upstream commit a4809b98eb004fcbf7c4d45eb5a624d1c682bb73 ]
In lpfc_cleanup, there is an extraneous nlp_put for NPIV ports on the F_Port_Ctrl ndlp object. In cases when an ABTS is issued, the outstanding kref is needed for when a second XRI_ABORTED CQE is received. The final kref for the ndlp is designed to be decremented in lpfc_sli4_els_xri_aborted instead. Also, add a new log message to allow for future diagnostics when debugging related issues.
